Catalytic Conversion of Greenhouse Gases (CH4 & CO2) to Synthesis Gas.

      Аннотация: Catalytic reforming of methane (CH4) with carbon dioxide (CO2) known as dry reforming of methane (DRM) produces synthesis gas which is a mixture of hydrogen (H2) and carbon monoxide (CO). CH4 + CO2 ? 2CO +2H2 ?Ho = 247.3 kJ/mol, ?G = 61770-67.32T The DRM process has gained much attention these days because of reducing greenhouse gases (GHG) CO2 and CH4 from the atmosphere. In addition to reducing GHG, the DRM process produces valuable chemicals (CO+H2), provides a good approach to utilize biogas and natural gas with a significant amount of CO2, have good capability of chemical energy transmission system as compared to steam reforming and finally yields unit H2/CO ratio as desired for Fischer-Tropsch Synthesis. But the main issue associated with this process is catalyst deactivation due to carbon formation in two side reactions of DRM process. Need of high external energy and carbonaceous deactivation of catalysts keep this process far away from industries. So this book contain an overview of the process with all possible ways of reducing problems associated with it.
